Keep Protect Your FaceBook and Twitter Privacy

Surfing the web no longer a solo
activity. Facebook , Twitter , and
other social networks have quickly
become an integral part of the online
culture, and with them comes an
array of serious threats to your
privacy. In this article, I’ll identify
some of the key dangers of social
networking and offer a few easy
steps that you can take to stay safe
online. Social networking is built on
the idea of sharing information
openly and fostering a sense of
community. Unfortunately, an online
network of individuals who actively
share their experiences and seek
connections with other like-minded
people can be easy prey for hackers
engaged in social engineering and
phishing attacks. It’s important to
be aware of the threats and to use
discretion in all of your online
interactions.
Take
Care
Before
You
Share
Online
For
starters,
even in
an open
community of sharing, you should
observe commonsense boundaries.
As President Obama warned
students in his September address
to schools, “be careful what you
post on Facebook . Whatever you do,
it will be pulled up again later
somewhere in your life.” The core
truth of that statement can be
applied to any social networking
site, and possibly to the Internet as
a whole. As a general rule, refrain
from posting things online that you
will regret later. The odds are good
that someone, someday, will
stumble across it, and it may come
back to haunt you— especially if you
are planning to run for public office.
If you think that abstaining from
posting embarrassing or
inflammatory comments online ruins
the fun, you’re playing a dangerous
game. Remember who your friends
are, and know that a friend of a
friend can be an enemy.
Don’t Lose Sight of Who Your
Friends Are
When you write a Twitter tweet or
post a Facebook status update, you
have to keep your audience in mind.
More and more these days, we hear
stories about people who forgot that
their boss was part of their network
and then said things online that
resulted in their being reprimanded
or even fired. The adverse
consequences of posting
inappropriate on line comments
have become so commonplace—at
least anecdotally—that they have
earned an entry in the Urban
Dictionary: Facebook fired . Even
announcing something as seemingly
innocuous as “I’m bored” in a
status up - date during work hours
can have dire consequences if the
wrong people see it. With services
like Twitter, and with the recent
changes to Facebook that permit
any interested party to view and
search your updates, you really have
no way to hide.
Recognize the Visibility of Your
Posts
You’ve thought it through, and you
want to shout to the world how you
feel about having to work overtime
and during a weekend that you had
earmarked for recreational activities.
You have checked and double
checked, and you’ve determined that
your boss is not in your network, so
you let loose on the keyboard and
speak your mind. Unfortunately,
you’re not home free (figuratively
speaking) just yet. Being outside of
your network, your boss can’t see
your post directly, but if a Facebook
friend who is connected with your
boss comments on your status
update—even just to say “I
sympathize”— your boss may be
able to click on the link through the
friend and see your post. Go ahead,
be social. Share your trials and
tribulations with your growing
network of adoring followers. But
for your own safety, keep one
essential rule in mind: Never post
anything online that you wouldn’t be
comfortable having everyone you
know see—because eventually they
probably will see it.
Define the Parameters of Your
Privacy
Marrying privacy and social
networking may seem terribly
unintuitive. How can you be social
and open, and yet protect your
privacy? Well, just because you are
choosing to share some information
with a select group of people does
not necessarily mean that you want
to share everything with everyone, or
that you are indifferent about
whether the information you share is
visible to all. Facebook, in
particular, has drawn unwanted
attention in connection with various
privacy concerns. If you have used
Facebook for a while, you may have
noticed advertisements that
incorporate your friends’ names or
photos associated with them.
Facebook does provide privacy
controls for you to customize the
types of information available to
thirdparty applications. If you look
at the Facebook Ads tab of the
privacy controls, though, you’ll
notice that it doesn’t give you any
way to opt out of the internal
Facebook Ads. Instead, it states
(alarmingly) that “Facebook strives
to create relevant and interesting
advertisements to you and your
friends.”
Approach Tattletale Quizzes With
Caution
For many users, one of the primary
attractions of Facebook is the
virtually endless selection of games
and quizzes. And part of their allure
is their social aspect. In the
advergames, you compete against
your friends; through the quizzes,
you learn more about them while
being briefl y entertained. The ACLU
exposed problems with how much
information these quizzes and
games share, however. Typically,
when a Facebook user initiates a
game or quiz, a notice pops up to
declare that interacting with the
application requires opening access
to information; the notice also
provides the user the opportunity to
opt out and cancel, or to allow the
access to continue. The permission
page clearly informs the user up
front that allowing “access will let
[the application] pull your profile
information, photos, your friends’
info, and other content that it
requires to work.” Under the
circumstances, you may wonder (as
the ACLU has) why a game or quiz
application would “require” access
to your friends’ information in order
to work.
Facebook Policy Concerns in
Canada
Facebook’s privacy policies have
run afoul of the Canadian
government, too. Canada’s Privacy
Commissioner has determined that
those policies and practices violate
Canadian privacy regulations, and
has recommended various changes
Facebook should make to comply
with them. One of the
commissioner’s biggest concerns
involves the permanence of
accounts and account data.
Facebook offers users a way to
disable or deactivate an account,
but it doesn’t seem to provide a
method for completely deleting an
account. Photos and status updates
might be available long after a user
has shut down a Facebook profile.
And like the ACLU, the Canadian
government is unhappy about the
amount of user information that
Facebook shares with thirdparty
application providers.
Exercise the Privacy Controls You
Have
Although the concerns of the ACLU
and the Canadian government run a
little deeper, Facebook does offer
privacy controls for restricting or
denying access to information. Since
Facebook is a social networking site
designed for sharing information,
many of the settings are open by
default. It is up to you to access the
Privacy Settings and configure the
options as you see fit. For each
available setting, you can choose to
share information with Everyone,
with My Networks and Friends, with
Friends of Friends, or with Only
Friends; if you prefer, you can
customize the settings to finetune
access further.
Beware of Hijacking and Phishing
Scams
By its very nature, social networking
is all about socializing, which
means that users are more than
usually disposed to let their guard
down and share information. They
come to the network to expand their
professional connections,
reestablish contact with old friends,
and communicate in real time with
pals and peers. And for predatory
bad guys, launching social-
engineering and phishing attacks in
this convivial environment is like
shooting fish in a barrel. Most
people know not to respond to e-
mail requests from exiled Nigerian
royalty promising millions of dollars
in return for help smuggling the
money out of the country. (Anyone
who doesn’t know better probably
shouldn’t be on the Internet; such
people are a danger to themselves
and to others.) But what if a good
friend from high school whom you
haven’t seen in 18 years sends you
a message on Facebook explaining
how her wallet was stolen and her
car broke down, and asks you to
wire money to help her get home?
You might be less suspicious than
you should be. Attackers have
figured out that family and friends
are easy prey for sob stories of this
type. Using other attacks or
methods, they gain access to a
Facebook account and hijack it.
They change the password so that
the legitimate owner can’t get back
in, and then they proceed to reach
out to the friends of the hijacked
account and attempt to extort
money such a Facebook message or
e-mail plea, pick up the phone and
call the person directly to confirm its
legitimacy.
Don’t Let a Tiny URL Fool You
Another threat that has emerged
recently as a result of social
networking is the tiny-URL attack.
Some URLs are very long and don’t
work well in e-mail or in blog posts,
creating a need for URLshortening
services. In particular, Twitter, with
its 140-character limit, has made
the use of URL shortening services
such as Bit.ly a virtual necessity.
Unfortunately, attackers can exploit
a shortened URL to lure users into
accessing malicious Web sites.
Since the shortened URL consists of
a random collection of characters
that are unrelated to the actual URL,
users cannot easily determine
whether it is legitimate or phony.
TweetDeck, a very popular
application for sending messages in
Twitter, provides a ‘Show preview
information for short URLs’ option,
which offers some protection.
The preview window supplies details
about the shortened URL, including
the actual long URL that the link
leads to. If you aren’t using
TweetDeck for Twitter, or if you need
to deal with shortened URLs on
other sites and services, maintain a
healthy dose of skepticism about
what might lie behind the
obfuscated address that a message
points to.
